Density-related effect of red deer browsing on palatable and unpalatable tree species and forest regeneration dynamics

Bark stripping damage is a serious problem in some forest hunting grounds in Serbia. This study aimed at assessing the incidence and intensity of bark stripping by red deer in the fenced rearing centre ?Lomnicka Reka? (Mt. Veliki Jastrebac, central Serbia). The data were collected by detailed surveying of the entire rearing centre over spring and autumn 2008, 2009 and 2010. Our results show that, in spring and summer, it is exclusively broadleaf tree species that are bark stripped by red deer, mainly beech (86.3% or 536 trees) and hornbeam (10.1% or 63 trees). The incidence and intensity of bark stripping were the highest in the diameter class of 20-39.9 cm. Damaged trees were identified in all parts of the rearing centre, at all aspects and at different slopes. Beech bark was stripped over the period May-August, with the focus in June or July.

Enrichment Planting

Abstract Key message: The Enrichment Plantation of Akure Forest Reserve is one of the forests currently experiencing a 17-year-long post-disturbance following deforestation and fragmentation in Nigeria. Context: To better understand the contribution of enrichment planting on forest regeneration and restoration, when the Enrichment Plantation after 17 years of post-disturbance was examined. Aims: We studied the recruitment drive of aboveground and undergrowth stands of an Enrichment Plantation in the tropical forest reserve. We assess the trees diversity, species compositions, species richness, and growth forms of the vegetations. Methods: A total of 3(50m x50m) plots were sampled. A total of 47 aboveground tree species and 45 undergrowth stands from Enrichment Plantation were identified. A statistical analysis were used to quantified the data obtained from this resultsResults: The result shows an increase in the diversity and an even distribution of the species of the aboveground forest trees, compared to the undergrowth stands. Conversely, the aboveground forest trees have lower species richness as compared to the level of undergrowth stands. The sapling density was significantly higher than the aboveground tree of the. It was also observed that the aboveground forest trees and undergrowth stands are somewhat similar in species compositions, which implies that sapling recruitment is a key determinant of the tree species composition of the forest.Conclusion: It is then concluded that the method adopted for restoration encouraged species diversity in this successional forest among the aboveground trees species and undergrowth.

Not enough forest regeneration? Intensified silviculture and hunting bring success (essay) The influence of red deer, roe deer and chamois on forest regeneration is significant in Swiss forests, especially in mountain forests. Oak, silver fir and sycamore rarely regenerate without protection measures. Red deer populations have practically doubled over the last 20 years, and roe deer are found in every forest. Nevertheless, it is possible to have, even in Switzerland, a dense, site-appropriate forest regeneration. The conditions for this are close-to-nature silviculture over large areas, and hunting which is closely adapted to the condition of the forest. This approach is successful if it is accompanied by serious cooperation between forest services and hunters – a cooperation which is not seen as an end in itself but as a means of reaching agreed objectives. Success will not be achieved with compromises only and by following traditional approaches.
